FLYING MACHINE.

Application filed March 11, 1926, Serial No. 93,987, and in Sweden February 24, 1925.

My invention relates to flying machines and more particularly to that class known as hydro aeroplanes and my object is to provide means for, steering the machine when running on the ground or on the, sea, and further to provide a handy mechanlsm for operating said steering means in flight as well as with the machine running on the ground or on the sea.

The invention will be described hereinbelow in connection with flying machines having on the under side of their fusilage a swingably mounted rudder adapted to act in the running of the flying machine on the sea and having further a supporting and steering Wheel combined with said rudder adapted to steer the machine when running on the ground. The invention is characterised, chiefly, by the fact that a mechanism to operate the water rudder carrying the sup-' porting wheel is combined with the mechanism for operating the usual vertical air rudder of the flying machine. In the drawing, Fig. 1 is a diagrammatic side elevation, with part in section, of a flying machine in which means embodying the invention are provided. Fig. 2 is a top plan view of the water rudder with the supporting wheel carried thereby. Fig. 3 is a detail view of the mechanism to operate the vertical air rudder. Fig. 4 is a plan view and Fig. 5 is a front view of a modified form of the mounting of the hand-wheel of the controlling mechanism.

The drawing illustrates, by way of example, a flying machine having a pair of front supporting wheels 1 and pontoons- 2 to enable running of the machine both on the ground and on the sea. Provided in the middle of the machine at an appropriate distance behind the front supporting wheels 1 is a rudder 3 pivoted to the under side of the bottom of the fusilage 1 by means of a shaft 6 extending through the bottom of the fusilage and through suitable bearings 4. The rudder 3 is preferably stream-lined. Loosely mounted within an opening in said rudder is a supporting. wheel 5. Carried by the shaft 6 above the upper bearing 1 is a worm-wheel 7 meshing with a worm formed on a horizontal shaft 8 connected, as by a rope transmission 9, to arms 11 attached to the operating shaft 10, one such arm only being shown on the drawing.

The operating shaft 1.0 is rotatably and slidably mounted in a framework 12 and jecting arm 21 of the horizontal rudder 22.

Upon rotation of the hand-wheel 24 in either direction the rudder 3 with the wheel 5 as well as the rudder 16 will be moved by the connections described, the arrangement being such that the rudders 3' and 16 will move in the same direction. Whether the machine is traveling w in the air, on the ground, or on the sea, it is only necessary in order to effect side steering that the pilot operatesthe hand-wheel 2d. If the handwheel 24 with the shaft 10 is pushed forwardly or rearwardly, that is, from or towards the pilot, respectively, the horizontal rudder 22 will be turned downwardly or upwardly, respectively.

In Figs. 4 and 5" I have shown a modified form of the mounting of the operating or control shaft 10 in which said shaft 10 is not' only rotatable and slidable but also capable of transverse swinging movement. To this effect any appropriate mounting arrangement may be used, provided it permits said three movements, as, for instance, a rotatably mounted spherical journal, through which, the shaft slidably extends. A guiding are 25 may, preferably, be provided to guide the shaft in' its transverse swinging movements. The swinging movement of the shaft 10 may be used to hold the flyingmachine in equilibrium or balance inasmuch as the shaft is connected by ropes 26 to endless ropes or the like carried by disks'28, rope wheels 29 rigidly connectedto the disks 28 being provided to guide and move ropes 30 connected to the balancing planes of the flying machine. I

It is thus seen that all movements as required to balance the flying machine as well as to steer it in the air or on the ground or sea may hand-wheel.

What I claim is:

1. In a flying machine ofthe hydro aeroplane type, a body, a vertical air rudder ivoted thereon, a stream-lined water ru der be operated by means of a common pivoted on the under side of said body, a

ground wheel mounted in and movable -with the water rudder and projecting slightly below the latter, a horizontal elevating rudder pivoted on said body, control members connected with said rudders, a rotary and axially movable operating shaft, actuating means operable bythe rotation of the shaft for operating the control members connected with the vertical and water rudders, and

actuating means operable by the axial movement of the shaft'for operating the control members connected with the horizontal rudder.

' 2. In a flying machine of the hydro aeroplane type, a body, a vertical air'rudder'pivoted thereon, a stream-lined water rudder pivoted on the underside of said body, a

ground wheel mounted in and movable with the water rudder and projecting slightly below the latter, a horizontal elevating rudder pivoted on said body, control members connected with said rudders, a rotaryiand axially movable ioperating shaft, actuating means operable by the rotation of the shaft .for operating the control membersconnected with the vertical and water rudders, actuating means operable by the axial movement of the shaft for. operating the control mom bers connected with the horizontal rudder and ahand wheel on the shaft for rotating and moving the same axially. I

3. In a flying machine of the'character described, a body, a vertical air rudderpivr oted thereon,'a,water rudder on the underside of said body, a shaft pivotally connect;

ing the water rudder to said body, a worm wheel on-the shaft, a horizontal worm-shaft meshing with said wheel, a rotary and axially movable operating shaft, a rope transmission operable by the 'rotation" of the operating shaft tosrotate said -Wheel thereby swinging. the horizontal rudder.

4. 'In a flying machine of he plane type, a body,ja vertical air rudder, a stream-lined water rudder on the underside of said body, a ground wheel mounted in hydro aero said water rudder to beenelosed therein ex- I cept for: its lowermost portion so as to serve as steering wheel in the movementof the aeroplane on the ground, .a common controlling mechanism for said rudders, including a rotatable and slidableshaft with a handwheel, the rotation-of which moves-said rudders in synchronism, an .elevatingrudder', and connections between sald elevating rudder and said shaft to permit controlling said elevating rudder by moving said hand-Wheel forwardly and rearwardly In testimony whereof I ,have signed my name.
